Hello Guys. On my post "A knife start to finish" I show some pictures about a straightening blades technique. Many people liked. So I made a short and very simple video to show it for you. Obviously I'm not here to tay that is a better method. Exist many interesting methods and I respect all of them.
Please sorry about my language. I'm learning speak english and just trying to help. God blesses you all! Hugs!

Thank you, this is great! Is the hammer a high hardness to work on a hardened blade?

And your English is easy to understand!
 
Thank you my brothers. I forgot to important information. I recommend you to make a hardening of your straightening hammer, and make a aneeling for fifteen minutes. Example: If you aneeling O1 steel for 1 hour at 480°F, make only the same temperature for 15 minutes!
Proceed the straightening blade with is hardening an aneeling! Regards!
 
Eduardo, I try to speak Spanish a little bit as a second language- my Spanish is no where near as good as your English! I think you are succeeding admirably at the difficult goal of fluency in another tongue.

Thanks for contributing this video, I love to see how smiths in other parts of the world do things and this is a great example of a very useful trick that I've not seen in use in America. It has the feel of an old world/European cutler's type of method.

I'm not saying I'm looking forward to trying it, as I hate blade warp, but when it inevitably happens, I'm very interested to employ this new method.

This is the kind of content that has made and will continue to make this forum quite a valuable resource.

His words leave me very happy brother Saleem. It's great to help in any way!
 
Eduardo, thank you for the tutorial. This is a method I have used before many years ago in my fabrication days to straighten smaller bar stock and had long forgotten. A trick my Grandfather (USN retired Master Chief Machinist Mate) taught me when he taught me most of what I know about metal and fabrication.

I will +1 the quality of your English. It is by far better than any secondary language I have 'attempted' to learn and speak.

Dear Marc is very nice to have made you remember your beloved grandfather. I consider this the best of the straightening techniques I know. It's simple, easy and fast. Thank you for writing your impressions here, my brother. God always be with you!
 
Thanks so much. Your English is fine. I will try your method next time I have a warped blade.
I hope you will post a picture of that knife when you are finished. Beautiful design and lines.
 
Thanks Eduardo - interesting technique; looks very effective!

One minor correction - I believe when you say "anneal" you mean "temper"

Thanks again for the informative video!

Dick, I really do not how to say. The hardening on oil in Brazil we called "têmpera". The heat treatment after, to reduce excessive hardeness, at one or 2 hours in the oven we called "revenimento". That is called "aneeling"? Do I correct? Please, teach me! Thanks!
 
Excellent video! Your method is essential the same used in the past by "Saw Doctors" to adjust saw blades. I have a book that details their work methods, but it never occurred to me to them on knife blades. Thanks for the tip!
